On thi'sgear Ljets `of steam to the work;

gli

the hub 11 is supported to rotate therewith. and to the hub 11 the hat form 12 is detachably mounted, as by means of the connecting or dowel pins 13 and 14, the former being located at the center of the hub and the latter, two being shown, being located outwardly thereof. The number of connecting pins used is a matter of detail. rlhe hat forni shown comprises the rim forming portion or base 121 and the crown 12".

The gear is driven by the gear 13, which is mounted upon the upper end of the pendant vertical shaft 14, which is journaled on the table top 5 in the bearing 15. The lower end of the shaft 14 is equipped with a clutch element or sleeve 16, which is keyed thereto for sliding movement and for rotatable movement therewith. VThis slidablevclutch sleeve is designed to engage the iXed clutch element 17, which is mounted on the upper 4end of a vertical shaft 18. The upper end of shaft 18 is supported in axial alignment with the pendant shaft 14 by means'of a bracket 19, .which is mounted against the bottom face of the `table top Aand which has a pendant arm through which the upper endof the shaft 18 and its clutch element rotate.

The vertical shaft 18 carriesthe gear 20, and said shaft extends through the bearing 21, which issupported by the frame bracket 21, one end of which is secured to the underside of the table leg, and the other end of which. extends upwardly and is bolted at 5n to thetable top. rllhe eXtreme lower end of the vertical shaft 18 carries the intermediate bevel gear 22, which is in mesh with the bevel gear 23, loosely mounted on the horizontal shaft 24, which extends throughthe vertical and upstanding arms 25 and 26 of the U- shaped bracket 27. This shaft also carries the second bevel gear 28, which is in mesh with the bevel gear 22 of the vertical shaft 18 and said gear 28 is also loosely mounted.

A clutch sleeve 29 is mounted on the shaft 24, and splined thereto forrlimited sliding movement, to engage the clutch teeth 23a of the gear 23, while a similar clutch sleeve 30 is splined to the same shaft for limited sliding movement to engage the opposite bevel gear 28, which is provided with clutch teeth 28a. A shaft 31 is coupled at one end to the shaft 24 and another shaft 32 is coupled at the opposite end of said shaft 24, the former working in the bearing 31a, and the latter working in the bearing 32a. The arm 33 of the Spanner 35 engages the sliding clutch sleeve 29, and the second arm 34 of said Spanner engages the clutch sleeve 30. The horizontal bar of this Spanner works in a guideway or track 36 provided on the bracket 27.

rlhe gear 20 meshes with a gear 36 which is carried by the vertical shaft 37, the lower end of which is round and the upper end portion of which is squared at 37 a. The eX- treme lower end of the vertical shaft is swiveled as at 37b to the vertical bearing 32` which extends downwardly from the cast frame bracket 21a.

On the squared upper portion of the shaft 37 the tubular screw 38 is mounted, the upper end of which has threaded engagement with the nutv 39, which is mounted on the table top 5. The nut 39 is formed integral with the right and left wings 39a and 39", which carry tubular guides 39a and 39h. The eX treme upper end of the screw is connected by the small coupling screw 40 with the cross head 41, one end ofwhich carries the depending guide rod 42 and the other end of which carries the depending guide rod 43, the former working through the tubular guide 39a', and the latter working through the tubular guide 39V..

Onthe cross head 41 a pair of link members 44 and 45 are mounted in spaced relation to each other, and to these link members the companion link members 46 and 47 are pivoted. Pivot pins 48 and 49 are provided upon the underside of the profile tracing bar 50, and one end of the latter is equipped with a small follower or tracing wheel, which is designed to work along the track or profile groove 52 Yformed in the form profile block 53, which is supported on the upright post 54, for easy detachable mounting. Coil springs, like those shown in Fig. 3 above the cross head 41, encircle the pivot pins 48 and 49 and engage the links v46 and 47 whereby the wheel 51 will be yieldingly retained in the groove 52. v

One end of the profile tracing bar is equipped with a sectional rod.55, and has a spring slip joint connection at 56 therewithY so that local terminal pressure will always be maintained upon the hat to be built or worked upon.

`The outer end of the arm or bar is equipped with the combined ironing and smooth tool` and the hat braid laying tool 57, shown in detail in Fig. l10. This tool consists of the case 58, which is pivoted to the arm or bar 55, and in which the detachable working tool 59` is mounted. The tool head 59 is shown to be formed with a working face 59 adapted to snugly lay the braid or other material against the curved outer surface of thc hat form 12, and the heel part 60, which is secured in the case 58. The tool head`59 carries the guide rods 59u and 59b which extend through the heel part 60 andare equipped with suitable terminal stops. A coil spring 61 is located between the tool head and the heel part for maintaining terminal pressure upon the tool head at the point of application.

The tool head is heated electrically by means through eyes 58aL provided on the case 58, as

` shown in Fig. 4.` The braid Vpasses over the roller64, supported above ythe hat `iorin 12,

whichr serves to temper the adhesive applied to the braid by nmeans ofthe drum `coating device 65, which is drivenby power from` the y verticalshaft 66,the upper endo;F which gear 69.` This gear is in driving enga with thefintermediate gear 70, which meshes carries thesinall bevel gear 67 to `engage with.

The rotation of the hat form shaft 18 is controlled independently by means Vof the lever 8,2,which operates the `clutch 16.; this lever being pivoted at 82a to operate by hand, upon a downward stroke" of the outer end of the lever, which extends forwardly oi the ma-` chine.

The vertical `shatt 66 which transmits 1no- V tionv to the geartiani of the adhesivecoating device, is equipped with a clutch element 66L which is engaged by the slid-ing clutch eleor controllingthe cirment G61 on the same shaft, and this is shifted bymeansot the lever 8,3 pivoted upon the arm 84and arranged to be operated'wholly by hand. The braid or hat making material isheld against the ifeed roller by means of the presseifroller 85. Y i r:The lowerendot.theshaft 66 works in the bearing 06 and is equipped with `the gear 86,

\ which is driven by the gear 87, and tliisgear 87 is carried by asmall transfer shaft .-88, supported at 89 on the i'rainebracket 21a.

" The shaft 88 also carries a pinion gear 90 which is driven by the gear 20 of the vertical Shaft 18.

1n Figs. llfand 12 I show almodiiied type i i et working toolywhiclh isfadapted to be used Vin connection with'the bar 50, afterthe standard braid working tool is removed,"for work Ving upon oldcrnew felthats.` This inodilied 4 tool comprises the carrying bar 91, `whichis adapted to havea spring slip fit with the bar 50, asshown in detail in Fig. 9. On the outer end of thebar 91 the yoke 92 .is

mounted. VThis yoke is equipped with a pair of spaced arms 93 and 94 between which the outer end or" the bar 91 is pivoted by the bolt 95. The arms93' and 94are`formed with arcuate slots 93a and 94a. .Through each slot a stud pin 95', carriedby the bar 91, projects and this pin is engaged by the spring 9b atene end, the opposite endet the spring bearing against the yoke to maintain saine in an approximately central ,position on the bar91. The yoke 92 isurther'equipped with integral sockets 97 and' 98, located on theends thereof. In the socket 97 the rod 97? works to compress the spring 98h, while inthe socket 98 the rod 98a works to compress a compresf" sion spring.` These rods 97a and 98`nlarelconnected at their'forward ends to thecase 99,` the bottom` wall 99* of which is perforatedl to allow steam to escape from thechamber 100,.betweeiji said bcttomwall 992L and the inner wall 101, whichV is imperorate. An electric heating unit 102 is arranged in the inner chamber `103 oi said case, being supplied with current through thewires of the feed cable 104, while steam is independently supplied to the chamber 100 by means of the steam tube 105. v

fili

In Fig. 13 a brush head 10G is shown, Which is designed for connection by the rods 107, one only being shown, to the yole 92, in the manner illustrated and described With reference to the equipment shown in Fig. 11.

The gear 13 is equipped with an arm 13)n which engages the angular arm 108 of the valve handle 108, shown in plan in Fig. 3. This handle controls the flow of steam from the steam cock or valve 108C to the steam tube 105 from the supply pipe 109. The handle 108a is also provided With a small arm or linger 108b Which is designed to alternately engage the spring pins 110 and 111 shown in detail in Fig. 8. Vhen the gearing is reversed for any reason the pin or arm 13a of the gear 13 Will reverse the position of the valve handle so that the small finger or arm 108b Will engage a ditlerent spring pin. In this Way intermittent jets of steam will be delivered to the compound head shown in Figs. 11 and 12, When the same is used. A nanual valve 112 is provided tor closing the steam supply independently.

Operation In making a braid hat; the operator locates the braid on the rim of the hat form 12, and then manually throws the main control lever 7 8 to start the machine. This operation results in the shaft 18 being driven, and motion being transmitted from the gear 13 to the gear 10, thereby rotating the hat torni 12. The braid passes through the guides 58- on the case 58 and under the con cave face 59 of the tool head 59, which is kept at the proper working temperature by the electrical heating unit. As the hat form is rotated, the tool head is gradually elevated until it reaches the center of the crown at the top of the form. The operator closely Watches the laying ot the braids, and when the crown is finished as above, he then, as by a hand scissors or knife, cuts oft' the braid, and at this period manually disconnects the feed drive for the braids by means of the lever 83. After the hat is taken from the form it may be stitched and subjected to any finishing operations required. At the instant the tool head 59 reaches a position atop and somewhat above the hat form 12, to per mit snipping the braid as already mentioned, the pin 73a on the screw 38 has reached a point Where it engages the adjacent end of the sliding bar 74, thereby rocking the bellcrank lever 77 against the control lever 7 8 and throws the latter to reverse position; this causing the screw to reverse the direction of its position, thus lowering the bar 50 and the tool head to restore the latter to its initial position offset from the periphery of the brim of the hat form 12, so that the hat may be removed. l/Vhen the screw reaches the lower limit ot its travel the circuit closer 79 is set to close the solenoid circuit and the solenoidsliifts the lever 7 8 to neutral position. Should the operator at any time desire to stop the rotation of the hat form, regardless of the continuing operation of any other of the mechanisms, he accomplishes this by manual operation ot lever 82.

In employing the machine for treating felt hats, the tools hereinabove mentioned are substituted as and when required on the tool carrier 50. Assuming any selected one of these tools non7 to be on such bar 50, the oper` ation of the machine proceeds as above, as alii'ected by the manual and automatic controls as already explained, exactly as has been already described; except that it will be noted that by a proper setting of the lever 83 the braid feeding mechanism is rendered and maintained inoperative.

The hereinbefore described construction admits ot considerable inodilieation Without departing from the invention; therefore, I do not Wish to be limited to the precise arrangements shown and described, Which are, as aforesaid, by Way ot illustration merely.
